IMPROVEMENT IN HOISTING-MACHINES.

Specification forming part of Letters Patent No. 116,607, dated July 4,1871.

To alt wilma it may concern:

Be it known that I, VILLIAM M. LLOYD, oi" the city, county, and State otNew York, have invented a newand useful I mprovement in HoistingApparatus g and Ido hereby declarethat the following is a i'ull, clear,and exact description thereof, which will enable others skilled in theart to make and use the same, reieri-mce being had to the accompanyi n gdrawing ti'rrming part ot' this specification The object of thisinvention is to provide cheap and convenient means for elevating bricksand mortar in the erection o1" buildings, and to be em` lo \'ed for allpurposes For which it maybe adapted; audit consists in two plati'brms orears, with 'the parts eonnwzted therewith, so constructed and arrangedas to rise and tall alternately, and to balance (or ne-.trly balance)each other, the arrangement bein g as hereinafter described.

In the aceompanyinyingdrawing, lfigure l represents a side elevation ot'the aplnu'atus. Fig. i. is a top or plan view.

Similar letters oi'reterenee indicate corresponding parts.

The line A is the basement or lower i'loor oi' a building. B is thesecondimir; and (l, the third Itloor. l) l)l) arestamlards, guides, orways, which. are extended from the lower lloor upward from one floor toanother as the buildin g progresses. The rays are constructed so as tosplice onto each other as they are required, andare grooved or otherwisemade to guide the ears orplatforms in aseendin and descending. E Erepresent the ears or platibrms upon which the load is placed t'orraising and lowering. F is the platform proper or bottom of the car. Theear is composed ofthe bottom F, side pieces G or uprights, and acrosspieee., II, to the latter ot' which the hoisting-rope I isattached. From the cars the lmisting-ropes pass upward over pulleys J',supported on top of the floor-timbers, as seen in Fig. l, and fromthence down to the lower Hoor and under pulleys K K, and then extendhorizontally onto the driving-drum L. (,)ne ot' the ropes is attached toone side and the other rope to the` other side ot' the drum, so thatwhen the drum is turned round or revolved, one rope will be wound uparound the drum and one of the cars elevated, while the other rope willbe unwound and the other car will descend.

A horse may be attaehei'l to thc lever M for revolving the drum., or thedrum may be revolved by hand, or steam-power may be used, the motion of'the drum being reversed as ot'ten as the ears reach theirlimit oli'ascent or descent. Any ot' the well-known devices for stopping'andholding` the cars in any desired position may be adopted.

N represents hods for eimtaining the mortar and bricks as placed on andsupported by the ears in ascending and descending.

This a-plmratus is well adapted li'orusein stores and warehouses, forraising' and lowering goods and merehamlise; butI designitmoreespecially for raisin buildingmaterials, thereby substitutinghorse ]`)owm' or other motive power for the laborious and slow processnow in common use for that purpose. To the builder the ad vantages ot'this mode ol" elevating his brick, mortar, and stone or other materialused, are ofthe greatest importance, as, by the common method, he iscompelled to double the number oii his hodearriers as his buildingprogresses from one story to another.

This a] paratus is simple aml cheap, and lnay be eonstructial and keptin, repair without resorting to the iron 1nachine-shops forgear-whcelsor other expensive portions ot' ordinary elevators.

From oneto the otheroil the uprights G of the cars there are one or morehorizontal rods, N, for supporting the hods in an uprightposition whenloaded, there being a hook on the hods which hooks over the rod. Therods N also serve to bind the uprights together and strengthen the car.

Having thus described my invention, I claim a-s new and desire to secureby Letters .Patent- The cars E, stands or guides D l) l), ropes I I,pulleys J and K, and drum L, constructed and arranged to operatesubstantially as and for the purpose hereinafter shown and described.

The above specification ot' my invention signed by me this 16th day ofJanuary, 1571.
